RadioGroup的使用非常简单,只是一般情况下.只能是横向排列或竖向排列.如果让多横排列的的就不是那么简单的了.
也许有童鞋该说了.将RadioButton写到LinearLayout中不久行了吗? 经过检验确实可以那样做,刚开始我也是这样做到.不过运行起来发现了了一个bug ---单选按钮不在是单选了.而且选择事件不会被监听到.这就要求我们去想办法了.其实实现起来也不难.只要多用几个RadioGroup就可以了(要在代码中处理一些事件).
1.xml中的布局:
<RelativeLayout
android:id="@+id/main_tab_container"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:paddingTop="30dp">
<RadioGroup
android:id="@+id/radio1"
android:layout_width="match_parent"
android:layout_height="60dp"
android:layout_margin="5dp"
android:orientation="horizontal">
<RadioButton
android:id="@+id/rb_1"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:textSize="@dimen/RB_text_size"
android:text="GBP英镑" />
<RadioButton
android:id="@+id/rb_2"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:textSize="@dimen/RB_text_size"
android:text="HKD港元" />
<RadioButton
android:id="@+id/rb_3"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:textSize="@dimen/RB_text_size"
android:text="USD美元Ԫ" />
</RadioGroup>
<RadioGroup
android:id="@+id/radio2"
android:layout_width="match_parent"
android:layout_height="60dp"
android:layout_below="@+id/radio1"
android:layout_margin="5dp"
android:orientation="horizontal">
<RadioButton
android:id="@+id/rb_4"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:textSize="@dimen/RB_text_size"
android:text="CHF瑞士法郎" />
<RadioButton
android:id="@+id/rb_5"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:textSize="@dimen/RB_text_size"
android:text="SGD新加坡元" />
<RadioButton
android:id="@+id/rb_6"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:textSize="@dimen/RB_text_size"
android:text="SEK瑞典克朗" />
</RadioGroup>
<RadioGroup
android:id="@+id/radio3"
android:layout_width="match_parent"
android:layout_height="60dp"
android:layout_below="@+id/radio2"
android:layout_margin="5dp"
android:orientation="horizontal">
<RadioButton
android:id="@+id/rb_7"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:textSize="@dimen/RB_text_size"
android:text="JPY日元" />
<RadioButton
android:id="@+id/rb_8"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:textSize="@dimen/RB_text_size"
android:text="CAD加拿大元Ԫ" />
<RadioButton
android:id="@+id/rb_9"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:textSize="@dimen/RB_text_size"
android:text="AUD澳大利亚元" />
</RadioGroup>
<RadioGroup
android:id="@+id/radio4"
android:layout_width="match_parent"
android:layout_height="60dp"
android:layout_below="@+id/radio3"
android:layout_margin="5dp"
android:orientation="horizontal">
<RadioButton
android:id="@+id/rb_10"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textSize="@dimen/RB_text_size"
android:text="EOR欧元Ԫ" />
</RadioGroup>
</RelativeLayout>
这样就实现了多行布局,这只是我布局中的一部分,其中 android:textSize=”@dimen/RB_text_size” 为自己定义的字体大小.
2,activity中的使用以及处理:
public class SelectMoneyActivity extends BaseActivity {
String strBtnSelected = ""; //记录选择的是哪个选项
private RadioGroup rg1, rg2, rg3, rg4;
private RadioButton rb_1, rb_2, rb_3, rb_4, rb_5, rb_6, rb_7, rb_8, rb_9, rb_10;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_select_money);
initView();
}
private void initView() {
rg1 = (RadioGroup) findViewById(R.id.radio1);
rg2 = (RadioGroup) findViewById(R.id.radio2);
rg3 = (RadioGroup) findViewById(R.id.radio3);
rg4 = (RadioGroup) findViewById(R.id.radio4);
rb_1 = (RadioButton) findViewById(R.id.rb_1);
rb_2 = (RadioButton) findViewById(R.id.rb_2);
rb_3 = (RadioButton) findViewById(R.id.rb_3);
rb_4 = (RadioButton) findViewById(R.id.rb_4);
rb_5 = (RadioButton) findViewById(R.id.rb_5);
rb_6 = (RadioButton) findViewById(R.id.rb_6);
rb_7 = (RadioButton) findViewById(R.id.rb_7);
rb_8 = (RadioButton) findViewById(R.id.rb_8);
rb_9 = (RadioButton) findViewById(R.id.rb_9);
rb_10 = (RadioButton) findViewById(R.id.rb_10);
btn_back = (Button) findViewById(R.id.btn_back);
btn_next = (Button) findViewById(R.id.btn_next);
//创建监听器,为每个RadioButton注册监听
BtnSelected btnSelected1 = new BtnSelected("1");
BtnSelected btnSelected2 = new BtnSelected("2");
BtnSelected btnSelected3 = new BtnSelected("3");
BtnSelected btnSelected4 = new BtnSelected("4");
BtnSelected btnSelected5 = new BtnSelected("5");
BtnSelected btnSelected6 = new BtnSelected("6");
BtnSelected btnSelected7 = new BtnSelected("7");
BtnSelected btnSelected8 = new BtnSelected("8");
BtnSelected btnSelected9 = new BtnSelected("9");
BtnSelected btnSelected10 = new BtnSelected("10");
rb_1.setOnClickListener(btnSelected1);
rb_2.setOnClickListener(btnSelected2);
rb_3.setOnClickListener(btnSelected3);
rb_4.setOnClickListener(btnSelected4);
rb_5.setOnClickListener(btnSelected5);
rb_6.setOnClickListener(btnSelected6);
rb_7.setOnClickListener(btnSelected7);
rb_8.setOnClickListener(btnSelected8);
rb_9.setOnClickListener(btnSelected9);
rb_10.setOnClickListener(btnSelected10);
//点击事件的监听器
public class BtnSelected implements View.OnClickListener {
private String btnId;
public BtnSelected(String str) {
btnId = str;
}
@Override
public void onClick(View v) {
strBtnSelected = btnId; //选择的某一项
isSelect = true;
//点击了第一行 ,就把另外行的点击项清空
if (btnId.equals("1") || btnId.equals("2") || btnId.equals("3")) {
rg2.clearCheck();
rg3.clearCheck();
rg4.clearCheck();
} else if (btnId.equals("4") || btnId.equals("5") || btnId.equals("6")) {
rg1.clearCheck();
rg3.clearCheck();
rg4.clearCheck();
} else if (btnId.equals("7") || btnId.equals("8") || btnId.equals("9")) {
rg1.clearCheck();
rg2.clearCheck();
rg4.clearCheck();
} else {
rg1.clearCheck();
rg2.clearCheck();
rg3.clearCheck();
}
}
}
}
已经搞定.还有一种方法就是自定义RadioGroup实现,不过这种有点复杂.我还是下班回家了.
